This is a pre Hammerite touchup!
I've left one hook on the pole in the 5 o'clock position and cut the other two off. All the poles were forced onto the ring and then hammered. They are a little stiff to bend out but that's perhaps no bad thing.
I've had a full 4 litre Dutch oven on it but I don't have a bigger one so can't help on that score. Suffice to say, there's no sign of the legs bowing, even though they are long...they also have good spikes on the end to push into the ground too.
